How to unattendedly apply regtweaks for default user, so that every created user preferably including default administrator will inherid HKCU registry from default user?

you mount the wim, mount the MountDir\Users\Default\NTUSER.DAT and modify it and unload. lot of trouble

might be best to just place a reg script in a location and call for each user. I know some do that

I tought about putting script to setupcomplete.cmd? But i'm to lazy to try it. But i guess, that since you mention only NTUSER.DAT, that somebody already tried it withouth success.

i apply mine in firstlogoncommands and they work. Commands in the Setupcomplete.cmd file are executed with local system privilege.

HKLM Reg tweaks can be ran here but not HKCU which are user specific.

Ok, one more thing before i try it - does this http://support.microsoft.com/?id=284193 still work in windows 7? This will be nice solution - i would just put script to runonce to HKCU_USERS and no need to attend and run scripts manually when new user log on for first time will be needed.

Hmm, i does not work, obviously, so i will just leave it and don't make default user settings in unattended installation.

Example and you can use dism

IMAGEX /MOUNTRW "D:\install.wim" 1 D:\zMountDir

REG LOAD HKU\Default D:\zMountDir\Users\Default\NTUSER.DAT

REM Configure the default user profile

REG ADD "HKU\Default\Control Panel\Sound" /v Beep /t REG_SZ /d NO /f

REG UNLOAD HKU\Default

IMAGEX /UNMOUNT /COMMIT D:\zMountDir
